1) a chemical formula may stand for a single atom or
molecule as well as a MOLE of the substance and 2) the ratios in correctly balanced equations can be used to determine the mass relationships among reactants and products in a chemical reaction We will begin with a typical problem that a chemical engineer might face in industry. Iron metal does not occur in native form to any appreciable extent. Most of it is found in the form of various oxides, iron(III) oxide being fairly common as an ore. This oxide is heated in an atmosphere of carbon monoxide to produce iron metal. Carbon dioxide is also a product of this process. How many grams of CO are needed to produce 1.0 kg of Fe?
